Safety Railing

If a safety railing is built around the heater, the minimum distances given in fig. 2 or in the railing's instructions for
installation must be observed.

Electrical connections

The heater may only be connected to the electrical network in accordance with the current
regulations by an authorised, professional electrician.
• Installation Images: 6.-7.
• The heater is semi-stationarily connected to the junction box on the sauna wall. The junction box must be splash-
proof, and its maximum height from the floor must not exceed 500 mm. (Figure 7)
• The connecting cable must be of rubber cable type H07RN-F or its equivalent. NOTE! Due to thermal
embrittlement, the use of PVC-insulated wire as the connecting cable of the heater is forbidden.
EN
• If the connecting and installation cables are higher than 1000 mm from the floor in the sauna or inside the
sauna room walls, they must be able to endure a minimum temperature of 170 °C when loaded (for example,
SSJ). Electrical equipment installed higher than 1000 mm from the sauna floor must be approved for use in a
temperature of 125 °C (marking T125).

Electric Heater Insulation Resistance

When performing the final inspection of the electrical installations, a "leakage" may be detected when measuring the
heater's insulation resistance. The reason for this is that the insulating material of the heating elements has absorbed
moisture from the air (storage, transport). After operating the heater for a few times, the moisture will be removed
from the heating elements.
Do not connect the power feed for the heater through an RCD (residual current device)!

Installation of the Control Unit and Sensor

The control unit includes detailed instructions for fastening the unit on the wall. Install the sensor as shown in figure 5.
Do not place the supply air vent so that the air flow cools the temperature sensor. Figure 11.

Resetting the Overheat Protector

See the instructions for use of the selected control unit model.
The reason for overheating must be resolved before resetting the overheat protector!
